Abstract (en)

A method for Layer 2 packet transmission is disclosed, wherein a corresponding relationship between packet attribute information and public MAC addresses is configured in an access device such that the access device could find a corresponding public MAC address in the corresponding relationship when receiving a packet from a user terminal, then replaces the source MAC address with the public MAC address found, and then sends the packet to a convergence layer device. A method for transmission of a Layer 2 packet without character information is also disclosed. The access device needs to obtain the packet attribute information and carry the information in the packet to be sent to the convergence layer device. An access device is also disclosed. As a result, the capacity of the VLAN and the MAC address table items needed for the convergence layer device to convert MAC addresses is greatly decreased.
